I’m with you (still using 98). I have one annoying problem. When I try to open movie files that I receive in e-mails, an error box appears that says, “STUDIO.EXE can not be found.” I can live with it. Whenever I see the windows logo on an attached file, I know that I cannot open it, so I just delete the message.
At some point one of the video file extensions got linked to installed and later removed STUDIO.EXE. It’s easy to check and fix - check your WIN.INI file in \WINDOWS folder for “STUDIO.EXE” under “[Extensions]” section, and check your registry for video extensions (.WMV, .MPG, .MPEG etc.) that are linked to STUDIO.EXE and replace it with your favorite video player.
Another way to do it is to tell your video player to associate itself with these extensions (most usually ask this during install, but have the option to do it later) - it should do the above by itself.
Hope it helps.
